Sheriff's deputies are investigating the death of a 27-year-old woman at the Reno home of a son of late casino mogul Bill Harrah but they said on Tuesday it does not appear suspicious.

The woman at Tony Harrah's house was identified as Elizabeth Manning. The exact cause of death has not been established, the Washoe County medical examiner's office said.

Tony Harrah, who is co-owner of Wild Island Adventure Sparks in Sparks, said in a statement that Manning was a close friend and daughter of an employee. He said that Manning had many health problems the last few years and had collapsed as she walked in his yard.

She was a University of Nevada, Reno graduate who was involved in social causes for children, he said.
